FindChangebyList with strings of text?

I'm trying to setup a findchangebylist document to change strings of text to match my company's verbiage. I've been successful changing items like:  $10.00 to read as $10 but I cannot get regular text like:  over-sized to read as oversized

More examples of text I'm trying to convert:

over-sized to oversized

CAT to CAT(R)   (adding the registration mark)

screenprint to screen print

Is this possible with this script?? There's over 100 words that follow this mindset. The custom dictionary isn't something that works, as it only checks for single words and not 2 words with a space inbetween.

Anything would be helpful.

Thanks!
